how do you sign out of spark 2.8.3, i dont see it in the menu for the user to sign out

It should be in the File menu and it is named Log out. If you don’t see it, your server probably has old version of Client Control installed or your admin has disabled the Log out option.

i have open fire server 4.0.3 , i upgraded my spark from 2.8.1 to 2.8.2 and lost the file menu, how do i add that to the server so that it keeps it enabled?

Update the Client Control plugin in Admin Console > Plugins.
